==Puppy's Init System==
Puppylinux uses the Busybox init process.
~"BusyBox combines tiny versions of many common UNIX utilities (GNU fileutils, shellutils,textutils) into a single small executable. It contains a small init system, which is a strippeddown SysVinit scheme. It can read an inittab file, but does not support runlevels" -- //Yvan & Frénot, A Survey of Unix Init Schemes [1]//
The name of the process is
%%Busybox init%%
The first script that his process called is referred to as the sysinit entry point, and it is defined in the file:
/etc/inittab
%%::sysinit:/etc/rc.d/rc.sysinit
tty1::respawn:/sbin/mingetty --autologin root tty1
tty2::respawn:/sbin/getty 38400 tty2
tty3::respawn:/sbin/getty 38400 tty3
::ctrlaltdel:/sbin/reboot%%
and from inspecting the above script we see that for puppylinux the sysinit entry point is:
/etc/rc.d/[[rc.sysinit]]
